SPECIFICATION forming part of Letters Patent No. 370,609, datedSeptember 27, 1887.

Application filed July 6, 1886. Serial No. 207,162.

To all whom it may concern: I

Be'it known that 1, CHARLES CLAPP, acitizen of the UnitedStates,residing at Trumansburg, in the-county of Tompkins, State of NewYork, have invented certain new and useful Improvements in Harvesters,of which the following is a description. 1

My invention has for its object the improvement of grain-bindingharvesters of the class in which the platforms are hinged to the mainframe-such, for example, as that patented by W. P. Hale August 25, 1885,No. 325,208, and also that shown in my application for a patent ongrain-binding harvesters, filed November 19, 1885, Serial No. 183,315. a

My present invention is intended to accomplish nearly the same objectsas the invention which is sought to be patented by the applicant justreferred to, but by other and improved means; and it relates to themanner of hinging the platform to the main frame and adj usting'itrelatively thereto, to maintaining the proper relative positions of theelevator andplatform carrier-belts during such adjustments, sosupporting the reel that it will follow the vertical adjustment ofthe-platform as well as the rise and fall of the grain end thereof as itpasses over undulating ground, and to raising both ends of the platformsimultaneously during vertical adjustment to secure its retaining ahorizontal position.

In the accompanying drawings, Figure 1 represents a plan or top view ofa harvester embodying my improvements, partly in section, on the line 11 of Figs. 2, 3, 4, and 5. Fig. 2 is a rear elevation of the same. Fig.3 is a vertical longitudinal section on the line 3 3 of Fig. 1. Fig. 4is a vertical transverse section through the platform and the pivotalpoints of its connection to the main frame on the line 4 4 of Figs. 1,2, and 3. Fig. 5 is a detailed front elevation, on an enlarged scale, ofa portion of the main frame and the mechanism attached thereto. Fig. 6is a plan view of the same, partly in horizontal section, on the line 66 of Fig. 5. Fig. 7 is an inside elevation of the same, with some of theparts in section and others partly broken away, for purposes of betterillustration. Fig. 8 is a detail plan view of the front hingedconnection, partly in section, on the line 8 8 of Fig. 5;

Fig. 9, a detail sectional view on the line 9 9 of Fig. 5; Fig. 10,asimilar view on the line 10 10 of Fig. 9; Fig. 11, a detail view of thereel-head detached. Figs. 12, 13, and 14 are detail views of amodification of the reeldriving devices, in which a Worm attached to oneof the apron-roller shafts and engaging a Worm-wheel on the reel-drivingtumbler-shaft is employed instead of mechanism shown in the main figuresof the drawings.

In its general features of construction my boards, F and bya verticalgrain board or divider, F to which is attached the guiding andsupporting mechanism of the grain-wheel. Within this frame thus formedis mounted the usual apron-roller frame,the front bar, G, of which liesagainst and is rigidly attached to the front sill of the platform,whilethe rear bar, G, is provided with spacing blocks between it and the rearsill,to which it is rigidly attached, the gearing for driving theplatformapron lying within this space inside of the rear frame bar. (SeeFig. 1.)v .At its rear corner the platform is attached to the main frameby means of a link, H, pivoted at h to the main frame,and provided atits other end with a loop, h, which embraces 'a hub or bracket, I,rigidly attached to the platform. At its front corner, in axial linewith this hub, the platform is pivoted to a sliding block, J, whichembraces and slides upon a guidebracket, K, rigidly attached to thefront cor- The guide-bar lg of this bracket, upon which the blockslides, is curved to an arc of acircle,the center of which is coincidentwith the pivot h of the link H,so that as the platform is raised itsfront and rear corners will move in parallel lines. It also IOU standsat an angle, as shown, to better adapt it to resist the side drafts andstrains to which it may be subjected in pulling the platform along.

The shoe J of the platform is provided with an arm or journal, j, whichpasses through a perforated lug, j, extending from the sliding block J,and this constitutes the front pivot of the platform. At its frontextremity the journal is squared at j for the reception of the squaresocket of a crank-arm,L,to behereinafter explained. The hub of thebracket I, at the rear corner of the frame, is bored to form a bearingfor the apron-driving shaft 1, which is provided at its outer end with achain sprocket-wheel, i, and at its inner end with a spur gear-wheel, i,engaging a similar wheel, t", on the shaft of the apron-driving roller9. As the shaft 1 does not move in a suitable direction to drive theapron-roller, these two wheels are employed to reverse the direction andgive the apron-roller its proper movement.

In order to vertically adjust the platform and support its weight, Iemploy two separate links, M M, provided with eyes at their lowerends,which embrace the wrist-pins at the front and rear corners of theplatform, and with gear-racks m m at their upper ends, which take intospur-pinionsn on ashaft,N,mounted in suitable hearings on top of themain frame. A bracket, N, on the top of the frame affords bearings for avertical shaft, N, which is provided at its upper end with acrank,n',within easy reach of the driver from the seat, and at its lowerend with a worm, a, which takes into a worm-wheel, a on theplatform-lifting shaft N. As will be easily understood, the turning ofthe crank will revolve the shaft, which through its pinions will raiseor lower the links connected to the wrist-pins on the platform. The wormand wheel are of such a pitch that they will hold the load at anydesired point, thus enabling me to dispense with a rack and lockingdetent, or such like mechanism. Projecting ears or lugs extend from thebracket-bearings N in which the liftingshaft is mounted, and areprovided at their extremities with anti-friction rollers n, which bearagainst the outer faces of the racks on the links and hold them intoengagement with the pinions.

As in my previously-mentioned application, N 0. 183,315, the rollers forthe upper or outer elevator apron, B, are mounted in a loose framecapable of endwise movement in suitable guideways in the main frame.These guideways consist of slots cut in the side walls of the mainframe, and through them extend guide-blocks,which slide therein. Theupper of these guide-blocks, b, constitute the bearings for thedriving-roller shaft B of the apron, while'the lower ones, I), are shownas consisting merely of bolts, which extend beyond the front and rearouter faces of the main frame. Notched lugs or projections m from theliftwith a stud-axle, 0, upon which the grainwheel is mounted, slides upand down on this guide-bracket,and at its rear side is provided with agear-rack, 0. A shaft, 0', mounted in suitable bearings on the end boardhasat its forward end a pinion, 0 which takes into the rack on thegrain-wheel block, and at its rear end,which projects beyond the rearbar of the platform, with a chain wheel or drum, o to which is attacheda lifting-chain, 0. At its inner end this chain is attached to the longarm of a bell crank lever, 0 pivoted at its heel to the main frame andprovided at the extremity of its short arm with an anti-friction roller,which rests upon the radius-link H. As the platform is raised orlowered,this link will move the short arm of the lever and cause itslonger pendent arm to swing toward or away from the chain-drum at theother end of the platform, and either draw off or pay on the chain woundthereon, thus causing the shaft to revolve and through its pinion, whichen gages the sliding block, to raise or lower the grain end of theplatform.

A guide-roller, 0 over which the chain passes, is mounted on a studsecured to the outer end of the rear sill immediately beneath the wristor hub I, so'that the rising and falling of the outer end of theplatform in passing over undulating ground will not materially affectthe mechanism to which itis vertically adjusted. As in mybefore-mentioned application, I employ a link or thrust bar, 1?,attached to the upper end of a lever, P, pivoted on the huh I andplaying through a slotted guide-plate, 1?, attached to the main frame,which permits free or independent motion of the grain end of theplatform within certain fixed limits and prevents the accidentalupsettingofthemain frame orits rolling overon the platform. In thiscase,however, the thrustbar is attached to the upper end of the lever ata point above the slotted guide-plate instead of below ita differencemerely of convenience and not of principle. The reel Qis mounted upon ablock, Q, pivotally connected to a sliding bracket, q, mounted upon twoguide-bars, q (1', attached to the front of the main frame, as shown bythe several figures of the drawings. The reel-head is bored to fit andturn upon a post or stud, Q rigidly sccured to the pivoted block, asshown, and at a point below where the reel-blades are attached it isprovided with a beveled gearwheel, Q, by means of which it is driven. A.split-bearing, Q, is formed in the block Q, in

which is mounted the hubof abeveled pinion, R, which takes into thewheel Q on the reel-head. v

To the upper end of the hub is suitably attached a tumbling-shaft, R,the upperend of which is feather-connected to the hubjof a beveledwheel, R intermeshing with a beveled pinion, r, on the front end of thereel-driving shaft 1, which is mounted in suitable bearings in the mainframe. The beveled wheel It is supported by a swinging bracket, 4*,suitablymounted upon the main frame concentrically with the axis of theshaft r, so that vertical adjustment of the reel-supporting head, whichwill vary the angle of the tumblingshaft, will not affect the relationof the beveled wheel R and pinion r. In order to maintain the properrelations between the reel and platform, the pivoted reel-supportingblock hasan arm or projection, g to which is at tached one end of aconnecting-link, L, the other end of which is connected to the squaresocketed crank-arm L, fixed to the wrist-pin j on theshoe oftheplatform, as before mentioned.

As will be readily understood, the undulatory movements of the outer endof the platform cause the crank-arm L to swing correspondingly, andthis, through its link-connection, will vibrate the supporting-block andraise or lower the grain end of the reel to correspond with the rise andfall of that end of the platform. r

The reel may be bodily set or adjusted to a greater or less height abovethe platform, as desired, the link-connection L being provided with aseries of holes, by means of which this point of attachment to thepivoted block Q may be changed to suit the height of the reel. In orderto make such an adjustment, the link is disconnected from the block andthe supporting-bracket q moved up or down on its guide-bars to thedesired position, when the link is again connected to theblock.

I have found in practice that the cross bars or slats fixed to the upperelevatorrapron have a tendency to throw the straws above thedrivingroller B out of reach of the overhead apron, D. To prevent suchstraws from being whipped over the roller B and out upon the platformagain, I pivot between the sides of the main frame a shutter or guard, Bwhich rests upon the guide-block 12 at each end of the apron-frame inclose proximity to the surface of the roller, and straws which mayaccidentally be drawn past the overhead apron, D, will be thrown againstthis shutter and fall back to a point within the influence of saidapron, and by it carried in proper direction on to the binding-table.The shutter being pivoted at one side and supported at the other by theguide blocks, will rise and fall with the apron frame and always keepthe opening above the roller B closed. Motion is communicated to thedriving-rollers of the platform and elevator'apron, and to theclearingroll and the reel, by means of a sprocket driving-chain, s, fromthe constantly-revolving shaft S on the main frame. This chain moves inthe direction of the arrows, passing from the driving sprocket-wheel 8around the wheel d, which drives the overhead apron, to the wheel e onthe clearing-roll, to the wheel 0 on the lower elevator-apron, to thewheel I) on the upper elevator-apron, to the wheel t on the platform, toan idle-wheel, S, mounted on a stud-axle projecting from the main frame,and

.from thence back to the driving-wheel from whence it started. As willbe seen by Fig. 2, the idle-wheel S and the wheel 0 are so situatedrelatively to the wheels t and b on the platform and upperelevator-apron, respectively, that they are nearly on a line drawnbetween these latter wheels, so that during the vertical adjustment ofthe platform, as one of the sections of chain 1) c or 13 s is lengthenedor shortened, the length of the other section will be oppositely changedto a corresponding degree, and no slackage will occur in the chain byreason of such adjustment, and consequentlyno take-up mechanism will benecessary.

stands as isnecessary to illustrate the modification; Fig. 13, a view,partly in section, on the line 13 13 of Fig. 12; and Fig. 14, a similarview on the line 14 14 of Fig. 12.

By means of the mechanism here employed I am enabled to dispense withthe separate reel-driving shaft 1*, and communicate motion to the reelby means of the clearing-roller shaft E, which projects beyond the frontof the main frame, and has mounted upon it a double-:

yoked casting, E. This casting has two bearings, e e, on the shaft E,and in a higher plane two other bearings, e e, at right angles to thefirst two, for the reception of the tumblingshaft R of the reel-head. Aworm, E is IIO mounted upon the shaft E between the bearings e e, and afeathered worm-wheel, Eiwhich is engaged by the worm, is on thetumblingshaft between the bearings e e.

It will readily be seen that the yoke will adjust itself to any anglethat may be given the tumbling-shaft by the elevation or rocking of thereel head, and that the shaft will move endwise to its bearings and theworm-wheel whenever a telescopic motion is desired. The

yoke is mounted on the shaft E between its bearing in the main frame anda fixed collar, 6 at the extremity of the shaft, thus preventing anyendwise motion of the yoke thereon.
